jxl.dll操作总结

1）Jxl是一个开源的Java Excel API项目，通过Jxl，Java可以很方便的操作微软的Excel文档。除了Jxl之外，还有Apache的一个POI项目，也可以操作Excel，两者相比之下：Jxl使用方便，但功能相对POI比较弱。

2）jxl.dll据说是一个韩国人写的，并且是用java语言写的。是通过一个ikvm的工具转换为jxl.dll供windows平台使用的。具体可以参照下面两个链接内容：

3）并且jxl不支持excel2007及以上的版本。

4）简要使用方法如下:

 using System;
 using System.Collections.Generic;
 using System.Text;
 using System.IO;
 using jxl;
 using jxl.write;
 namespace ExcelWrap
 {
     /// <summary>
     /// jxl.dll帮助类
     /// 说明:jxl不支持excel2007以上格式
     /// </summary>
     public class JxlHelper
     {

         public static void ReadExcel(string ExcelPath)
         { 

         try {

             //Create a workbook object from the file at specified location.
             //Change the path of the file as per the location on your computer.
             Workbook wrk1 =  Workbook.getWorkbook(new FileInfo(ExcelPath));

             //Obtain the reference to the first sheet in the workbook
             Sheet sheet1 = wrk1.getSheet();

             //Obtain reference to the Cell using getCell(int col, int row) method of sheet
             Cell colArow1 = sheet1.getCell(, );
             Cell colBrow1 = sheet1.getCell(, );
             Cell colArow2 = sheet1.getCell(, );

             //Read the contents of the Cell using getContents() method, which will return
             //it as a String
             String str_colArow1 = colArow1.getContents();
             String str_colBrow1 = colBrow1.getContents();
             String str_colArow2 = colArow2.getContents();

             //Display the cell contents
             System.Console.WriteLine("Contents of cell Col A Row 1: \""+str_colArow1 + "\"");
             System.Console.WriteLine("Contents of cell Col B Row 1: \""+str_colBrow1 + "\"");
             System.Console.WriteLine("Contents of cell Col A Row 2: \"" + str_colArow2 + "\"");

         }
         catch (jxl.read.biff.BiffException e)
         {
             Console.WriteLine(e.StackTrace);
         } catch (IOException e) {
             Console.WriteLine(e.StackTrace);
         }

         }

         public static void WriteExcel(string ExcelPath)
         {
           try {
             FileInfo exlFile = new FileInfo(ExcelPath);
             WritableWorkbook writableWorkbook = Workbook
                     .createWorkbook(exlFile);

             WritableSheet writableSheet = writableWorkbook.createSheet(
                     "Sheet1", );

             //Create Cells with contents of different data types.
             //Also specify the Cell coordinates in the constructor
             Label label = new Label(, , "Label (String)");
             System.DateTime dt = System.DateTime.Now;
             jxl.write.DateTime date = new jxl.write.DateTime(, , ref dt);
             jxl.write.Boolean bl = new jxl.write.Boolean(, , true);
             Number num = new Number(, , 9.99);

             //Add the created Cells to the sheet
             writableSheet.addCell(label);
             writableSheet.addCell(date);
             writableSheet.addCell(bl);
             writableSheet.addCell(num);

             //Write and close the workbook
             writableWorkbook.write();
             writableWorkbook.close();

         } catch (IOException e) {
             Console.WriteLine(e.StackTrace);
         } catch (jxl.write.biff.RowsExceededException e) {
             Console.WriteLine(e.StackTrace);
         } catch (WriteException e) {
             Console.WriteLine(e.StackTrace);
         }
         }
     }
 }

5)其他的使用方法可以参考java实现的例子。网上关于java的例子还是挺多的。之前我并不知道它是通过java转换而来的，也没有可以使用的例子，只有通过Reflector反编译看源码，慢慢了解。
